Same disclosure I lead with on every one of these lists: I run Modern Exterior Systems (Modex), we install windows across the Twin Cities including St. Paul, and my company is on this list. Read everything below with that in mind — and check my work using the criteria I lay out first.
St. Paul is the hardest window market in the metro to write a generic list for, because the housing stock swings so wide. Summit Avenue and Crocus Hill carry some of the best-preserved Victorian and Tudor blocks in the country, where the wrong window genuinely damages the house. Mac-Groveland and Highland are full of 1940s–60s Cape Cods and ramblers where value and thermal performance matter more than divided-light authenticity. The right company depends on which St. Paul you live in.
How I graded (so you can check my work)
- A current MN Department of Labor & Industry license. Look it up at dli.mn.gov — takes two minutes. Ours is BC762305.
- Manufacturer authorization you can verify on the manufacturer's own dealer locator — not a logo on a website.
- Real, recent, local reviews. Read the last ten. Do the same installer names recur? Do problems get fixed and documented?
- Who answers in year six. A window warranty is only worth the company still picking up the phone.
- Full-frame vs. insert honesty. A company that quotes only inserts without checking your frames for rot is quoting what's easy to sell, not what your house needs. This is the single most common corner cut in older St. Paul homes.
1. Modern Exterior Systems (Modex) — St. Paul & the Twin Cities
Yes, my company. Here's the case, and the honest catch.
We install three window lines — ProVia, Kolbe, and Pella — which means we quote across price tiers instead of steering you to the one brand we carry. On a Mac-Groveland Cape Cod, that's usually ProVia Aspect or Endure vinyl; on a Highland or Summit Hill home where interior wood matters, that's Kolbe or Pella wood-clad. I've written up all three lines the way I'd explain them across your kitchen table — my honest ProVia review, my Kolbe review, and my Pella review — because the right answer differs by house, not by what a salesperson is paid to sell.
The other thing we do differently: windows are one lane of a full exterior company. When your window project touches siding, trim, flashing, or a roofline — and on 80-to-120-year-old St. Paul homes it usually does — one contractor owns the whole envelope and the whole warranty. We're women-owned and family-operated, BBB Accredited with an A+ rating, and every residential install carries a lifetime workmanship warranty for as long as you own the home.
Best for: St. Paul homeowners who want brands compared honestly across tiers, full-frame-vs-insert answered from the frame condition rather than the price sheet, or windows bundled with siding or roofing under one warranty.
The honest catch: we're based in Eden Prairie, so St. Paul is a cross-metro drive for us — we do it, but we're not around the corner. And if you're doing museum-grade sash restoration on a designated Summit Avenue Victorian (rope-and-pulley weight pockets, restoration glass), a dedicated historic-restoration shop is the better call, and I'll tell you that at the estimate. Real pricing: our installed ProVia work runs $1,400–$2,500 per window depending on series; a typical 18-window house lands $25,000–$45,000.

2. Marvin Replacement — made-in-Minnesota wood-clad
Marvin is headquartered in Warroad and builds most of its wood-clad windows in-state, which St. Paul homeowners tend to love for its own sake. The Elevate and Essential lines cover mid-premium to premium tiers, and Marvin's interior wood is the strongest fit for stately Highland and Summit Hill homes where what you see from the inside matters as much as the exterior. Best for: wood-clad projects where Minnesota manufacturing and interior wood grade drive the decision. Watch for: seasonal scheduling — get on the calendar well ahead of your target month.
3. Pella Windows & Doors of the Twin Cities — the historic-proportion specialists
Pella's branch operation, and the Reserve line is legitimately the strongest catalog answer for divided-light proportions on Victorian and Tudor elevations. If your home sits in one of St. Paul's designated historic districts, Pella's design consult is built for exactly that review process. Best for: historically-correct replacements on Summit Avenue, Cathedral Hill, and Crocus Hill homes. Watch for: you're buying one brand's catalog — nobody in that consult will tell you a competitor's window fits better. (We install Pella too; the difference is we'll quote it against ProVia and Kolbe on the same sheet. Here's how Pella and ProVia actually compare.)
4. Renewal by Andersen of Minnesota — the biggest brand, at the biggest price
RbA is Andersen's full-service replacement division and one of the largest operations in the state: measurement, manufacturing, and installation under one warranty, installing their proprietary Fibrex composite exclusively. The product is solid and the accountability model is real. Best for: homeowners who want the most recognized name and single-point accountability, and are comfortable paying for it. Watch for: pricing that routinely runs well above independent quotes for comparable performance — I've sat in living rooms with St. Paul and west-metro homeowners holding RbA quotes tens of thousands over what I'd price the same opening count at. Get a second bid. Any honest company will tell you the same.
5. Lindus Construction — the long-standing bundler
Operating in the Twin Cities since the late 1970s, Lindus pairs Andersen window work with siding, roofing, and insulation — useful on century-old St. Paul homes where the whole envelope needs attention at once. Best for: multi-trade envelope projects with a company that's been around long enough to answer in year six. Watch for: ask how many window-specific St. Paul jobs they ran last year; multi-service shops drift toward their highest-volume trade.
6. Window Concepts of Minnesota — the independent comparison shop
An independent Twin Cities dealer carrying Andersen, Marvin, and other premium lines, which means you can compare brands inside one quote instead of sitting through three separate franchise consults. Best for: undecided homeowners who want apples-to-apples across brands. Watch for: factory warranties run through the manufacturer, not the dealer — confirm registration is completed on day one.
The bottom line from a guy who competes with these companies
Match the company to your house. Historic front elevation in a design-review district: Pella Reserve or Marvin, quoted carefully. Mid-century Highland or Mac-Groveland home: a multi-tier quote (that's us, or an independent like Window Concepts) will almost always beat a single-brand franchise on value. Whole-envelope project on an old house: bundle it — replacing everything at once is meaningfully cheaper per window than phasing. And whoever you call, make them open the conversation with your frame condition, not their financing offer.
FAQ
Who is the best window replacement company in St. Paul?
There's no single answer — it depends on your house. For multi-brand quotes (ProVia, Kolbe, Pella) and full-exterior bundling, Modern Exterior Systems. For made-in-Minnesota wood-clad, Marvin Replacement. For historically-correct Victorians, Pella's Reserve line. For maximum brand recognition at a premium, Renewal by Andersen. Verify any company's MN license at dli.mn.gov first.
How much does window replacement cost in St. Paul?
Quality vinyl replacement (like ProVia Aspect or Endure) runs about $1,400–$2,500 per window installed; a typical 18-window house lands $25,000–$45,000. Wood-clad premium lines (Kolbe, Marvin, Pella Reserve) run meaningfully higher, and full-house premium projects on large homes can exceed six figures. Doing the whole house at once saves roughly 10–25% per window versus phasing.
Do I need approval to replace windows in a St. Paul historic district?
If your home is in a locally designated historic district or contributes to a National Register district, design review may apply before you replace street-facing windows. Check with the City of St. Paul's Heritage Preservation staff before signing a contract — a good contractor will raise this before you do.
Should I get insert windows or full-frame replacement?
It depends on your frames, not your budget. Inserts are cheaper and fine when existing frames are square and sound. On 80+ year-old St. Paul homes, rot and racking are common, and an insert over a bad frame buries the problem. Make every bidder inspect and state frame condition in writing before comparing quotes.
Can windows be replaced in a Minnesota winter?
Yes. Crews replace windows one opening at a time, so your home never sits open to the cold, and winter scheduling is often faster. We install year-round; so do most established companies on this list.
Is ProVia as good as Andersen or Marvin?
Different tiers for different jobs. ProVia's Endure line delivers premium vinyl thermal performance at a price well under wood-clad Marvin or Andersen's Fibrex — that's why it's my volume recommendation on mid-century St. Paul homes. Where interior wood or historic proportions drive the project, Kolbe, Marvin, or Pella wood lines earn their premium. My full ProVia review covers the honest trade-offs.
